Horse head masks are most commonly made from latex, polyester, or plastic. Some styles also feature finishes like soft faux fur for added texture.
Many masks are labeled one-size-fits-most and list maximum head sizes around 24–26 inches. Some designs also include extended neck openings (for example, a 24" neck opening) for extra coverage.
Typical masks include eye openings and mouth openings for vision; some latex heads explicitly note additional holes at the mouth and nose to aid breathing and visibility.
These masks have flexible mouths designed to move with the wearer’s jaw. Product descriptions often note phrases like “features mouth movement” or “moves with your jaw.”
Coverage varies by style. Some costume heads include extended neck openings—for example a 24" neck opening—and product dimensions such as about 18" x 24" are cited for added coverage.
Most listings specify the headpiece itself (for example, “Includes: One Horse/Unicorn Costume Head”). One item in the set is an accessory—a fabric-covered headband with a sculpted face panel—instead of a full mask.
